Seven Swords of Sin was released at GenCon Indy 2007 and was the featured adventure in the first Gen Con Paizo Publishing "delve" event. The module's plot was written by James L. Sutter but its rooms were written via an internal Paizo "Deadliest Room Contest" in which many of the staff collaborated to make the most viscerally pleasing dungeon possible.

The powerful seductress Tirana has stolen the alara'hai, seven mighty blades, each tied to a deadly sin, and secreted them away to her monster-infested dungeon. Located in Kaer Maga, one of the most dangerous cities in all of Varisia, the trap-laden halls must be overcome before the sorceress can bind the swords to her will and gain unimaginable power.
